Patent GB-8415758-D0 (GB)
Title: Machine for making paper booklets
IPC: B65H45/24
Filed: 1984-06-20
Abstract: Apparatus is provided in which booklets of interleaved cigarette papers can be made from continuously moving strands of strip paper in which a cutting knife used to sever the paper strips precisely follows movement of the strip. Movement of a driven input shaft (51) is brought onto the moving platform (25) and used to operate the cutting knife (29). Paper from bobbins (10, 11) is converged by formers (15,17,18) and a spreader (16) into a strand advanced by nip rolls (21,22) through cutting station (25). The knife (29) in the station cuts a booklet from the strand while the station (25) moves with the strand. A driven rotatory shaft (76) of non-circular section transmits its rotation to sleeve (81) that slides therealong so the station (25) reciprocates relative to shaft (76). The sleeve (81) is operably connected e.g. by gearing or by a cam and follower to the knife (29) so that rotation thereof brings about the cutting movement.

Date Mar. 24, 1988.A method for the rapid and sensitive analysis of heavy metal ores, especially those of gold and uranium, uses high-engery X-ray fluorescence spectroscopy. The invention is of particular interest for the measurement of samples from gold or bodies which typically have concentrations up to 10 ppm by mass. Preferred features include the use of an X-ray tube as a source, the counting of emitted fluorescence photons in energy bands selected to correlate with the characteristic x-ray fluorescence emissions of elements of interest, the excitement of the ore sample by irradiation with high energy bremsstrahlung radiation filtered through tin, the exploitation of polarization in analysis for uranium, the interposition of a platinum-group metal filter between the sample and the detector, and the use of high-purity germanium detectors. Techniques are described for the detection and elimination of inaccuracies due to the presence of certain interfering metals and correction for variations in sample density. Apparatus for use in the method of the invention is also disclosed and claimed.

Abstract: The time (t0-t1) between the first signal (t0) for the turbine shaft rotation position and the second signal (t1) for the passage of a turbine tip is measured for at least three specific turbine blade angles (alpha1-alpha3) and any variation in this time is recorded in relation to the turbine output. The angular velocity (gamma) is also recorded, whilst the time values (t0-t1) are used as starting values for calculating the blade tip position in terms of x and y-coordinates for its intersection points (S0-1, S0-2, S1-2) or a centre of rotation (P, P) for the blade. Step sequences (a-d) for a suitable number of cycles are prepared to obtain these values over the blade tip intersection points (S) as a function of the respective blade angle, in order to generate a tangent curve (20) for the blade tip edges or determine the centre of rotation for the blade.  A sensor device (8) connected to the turbine shaft generates the first signal and a sensor device (16, 18) inside the turbine wheel chamber generates the second signal.
